Question

What is the gravitational acceleration on the board of the Deepsea Challenger when it is in the Mariana Trench, 11 km below the surface of the Pacific Ocean?

It is slightly less than 9.81 m/s2.
It is very large due to the high pressure.
It is zero.
It is significantly less than 9.81 m/s2.

Answer 1

The gravitational acceleration on the board of the Deepsea Challenger is slightly less than 9.81 m/s².

Step-by-step explanation:

The gravitational acceleration on the board of the Deepsea Challenger when it is in the Mariana Trench, 11 km below the surface of the Pacific Ocean, is slightly less than 9.81 m/s². The acceleration due to gravity decreases as you move further away from the Earth's surface, so at a depth of 11 km, the acceleration would be slightly less than the standard 9.81 m/s².
